How to Change an LG Microwave Light Bulb

Every LG microwave has a light bulb on the interior, so the user can easily see the contents inside the microwave. The bulb is turned on when the microwave door is opened, as well as when the microwave is in use. You may need to replace the light bulb as it will burn out over time. Although the bulb is an internal component of the microwave, it does not need to be sent out for servicing to be replaced.

Step 1

Disconnect the power to the microwave by unplugging it from the wall, or by turning off the circuit breaker.

Step 2

Open the microwave door, then unscrew and remove the two screws located on the vent grille. The vent grille is located on the top of the microwave, inside the area covered by the door when it is closed.

Step 3

Slide the grille to the left, then tilt it forward. Lift the grille out of the microwave's frame to remove it.

Step 4

Unscrew the mounting screw on the bulb holder, which is now exposed with the grille removed. Lift the bulb holder out of the microwave.

Step 5

Remove the bulb from the bulb holder by unscrewing it from the base.

Step 6

Insert a new 30-watt light bulb into the bulb holder, then replace the bulb holder and mounting screw. Replace the grille, securing it in place with the screws that were removed to complete the procedure.
